Stats Objectives

• Make the game more interesting and fun for fans and players

• Information for the media (primarily television) though summary reports are e-mailed to News organizations as well

• Information for players and coaches• Not a coaching tool but useful information to

analyze the opposition and the ice.

Stats Principles

• Straight forward – Easy to learn• Give the benefit of doubt to the curler• Shot evaluated according to shot called

• e.g. Bad call, impossible shot or improper broom placement does not factor into the evaluation of the shot

Scoring SystemHow to score shots

CCA Scoring System

• Record the turn, type of shot, and score• Four point system

• zero points for a complete miss• 4 points for a fully made shot

• No bonus points

CCA Scoring System

• Takeout Codes• A Straightforward hit• B Hit with roll requested• C Clear front stone or guard• D Raise takeout of rock in front

• Need to remember that a HIT is not coded as “H”, TAKE OUT is not coded as “T”

CCA Scoring System

• Draw Codes• E Draw to house

• Raise own front stone into house• Free guard zone split

• F Front stone• G Guard• H Freeze• J Tap back rock in house (own or

opponents)• Need to remember that a DRAW is not

coded as a “D”, a FREEZE is not coded as an “F” and a TAP is not coded as a “T”

CCA Scoring System

• Scoring is easy• 0 bad shot (did not improve the situation) • 1 improved situation slightly• 2 mediocre shot (improved situation but not

desired result) • 3 almost the desired result but not quite• 4 good shot (what one would normally

expect)

CCA Scoring System

• Throw through not counted• Unless missed (left in play)• Code as X X 0 on score sheet

• Unusual Situations• Rock removed from play for any reason is

zero points• Burned by sweepers• Hog line violation is coded “V” in the score column• Time violation

• Rock which picks is scored on result achieved (not all picks are misses)

Tips For Scorers

• Be consistent• Whether scoring tough or easy, all players

deserve equal treatment• Give benefit of doubt to player• Nothing is gained by being tough• These are curling’s elite – their stats should

be good

Tips For Scorers

• Note lefthanders during team practice prior to the game• Lefties have opposite rotation on in and out

turns• When using a scoresheet, place an “L” by the

player as a reminder• For direct entry, the screen will indicate a

lefthander

Tips For Scorers

• Be alert to players hitting out of turn• Each rock thrown is credited to the player

who threw it, adjust player number if necessary

• Clearly indicate on the scoring sheet where the order differed from normal

• Watch the skip for the called shot• Not all skips indicate the call clearly• Score generously on an ‘no call’ or ‘missed

call’

Tips For Scorers

• Watch for optional shots• Award full points for any properly executed

option. e.g.. Tick guard or get rock in house• Do not agonize a long time over any

given shot• Your first thought is likely the best• You may miss the call for the next shot• Change later if desired, but don’t leave a

blank value, it can’t be entered in the system

Tips For Scorers

• Ice conditions affect strategy and scoring• On swingy ice guards must be tighter and are

more difficult to position• On straight ice hits are simpler and draws

around guards more difficult• Where ice conditions have made a shot easier

or harder, one should raise or lower scoring standards

• Adjust points for realistic results• Adjust points for difficult shots e.g.. ‘pick’

style takeout where stay is not realistic. Award 4 points

Tips For Scorers

• Hit (A) vs Hit and Roll (B)• Code B must be a called hit and roll (not

accidental)• If the roll is optional, award full points for a

nose hit• The perfect hit and roll (except for roll out of

play) is a hard shot – use this code sparingly. If a roll is indicated but you are sure the skip would be happy with a nose hit, then use code A

Tips For Scorers

• Front stone (F) vs Guard (G)• A ‘corner or centre guard’ is a front stone F• A guard is any front stone specifically placed

to protect an existing stone• A draw to the rings which stops short of the

rings is code E

Tips For Scorers

• Game score or situation can affect the score for a shot• On skip’s last rock a draw which is not shot

but cuts the opponent down can be given 2 or 3 but in the last end where the shot is needed to win or tie this shot is either 0 or 4

• On skip’s last rock, if they must be full four foot in order to score a second point, the score is either 0 or 4, in this case close doesn’t count

Tips For Scorers

• Practise as a group and compare results• This will improve consistency (individual and

committee)• Score local super league games or other

competitions

Video PracticeA chance to score a couple of ends from video

Scoring Essentials

• Start on proper side of sheet• In the first end, note who has the hammer

and start of the correct side of the sheet• Put an asterisk beside the team name of the team

that has hammer for data entry• For each shot, indicate:

• Handle: I or O (beware of lefties)• Type of shot A B C D or E F G H J• Points: 0 to 4• V for hog line violation (0 points awarded by

program)• Enter score for the end

• Score for this end only (not game total)

Scorer Logistics

During game◦For the first end only, write the player’s name

under the player number on the sheet as they are actually throwing This alerts the Results Manager to a lineup change

◦Be alert to lefties to code proper turn◦Be alert to players throwing out of turn and

player substitutions◦Be alert to hog line violations, ‘V’ points◦Note:

Start each end on proper side of sheet Runner or supervisor will collect completed sheets

Scorer Logistics

When game is complete◦Code all throw throughs as X X 0◦Record score for final end (may be X X)◦Record final game time (after extra end if it

occurs)◦Check ‘End of Game’ box◦Make sure runner or supervisor gets your final

sheet

Runner/Spare

An essential role for events with data entry

Collects sheets from scorers in a sheet entry environment

Proof read scoresheet, checking score for end and data correct for each team◦Watch for missing number or codes and ask

scorer to completeMaintain linescore sheetCan fill in for another scorer if,

◦Someone doesn’t show up◦Someone has to leave during the game◦Someone needs a break during the game

Data Entry

For events that use sheet entry on some or all sheets, enters the scores into the program

One or two people◦With two people, one person typically reads the

sheet and the other person types, then the reverse to verify the data entered

Essential to have data entry people for sheet entry events (Results Manager is not the data entry person)

Supervisor Assistant

If there is no runner/spare◦Collects sheets from scorers in a sheet entry

environment◦Proof read scoresheet, checking score for end

and data correct for each team Watch for missing number or codes and ask scorer to

completeSpare for scorers or data entry personnelAssists Statistics Supervisor during each

draw as requiredMay be the supervisor at the second site

for 2 site events (eg. Juniors, Seniors)

Statistics Supervisor

Creates the master schedule◦Try to keep the number of scorers small◦Schedule scorers on the same sheet each time

Remember that the teams rotate across sheets so the scorers shouldn’t otherwise they may score the same team too many times

Makes sure that people are aware of when they are scheduled

Results Manager

◦Results Manager is responsible for the quality of the stats, ensures updates get to the internet, troubleshoots technical problems, etc.

◦In the early draws, the Results Manager needs to be coaching the scorers where necessary
